Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, BENNETT D. MARKS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Design-Rollers for Graining Wood or other Material upon Which it is Desired to Reproduce the Grain of the Wood, of which the following is a specification.

In design rollers for graining machines with which I am familiar it is customary to use a veneer, which is a thin section of wood bent in a curved or cylindrical form to encompass the cylinder or roller. Practice has shown that rollers constructed in this manner wear out very quickly on account of the extreme thinness of, the veneer and also get out of true very quickly, due to the swelling of the veneer, which is practically unavoidable, owing to the fact that it is immersedmost of the day in paint. Besides this there is a tendency for the wood to warp or crack the veneer, which is necessarily a very delicate surface.

The object of my invention is to overcome these difliculties and to provide a roller which will be free from the objections of the rollers constructed with the thin veneer. My method of obtaining this object may be more readily understood by having reference to the accompanying drawings, which are annexed hereto and are a part of this specification, in which Figure 1 is a side elevation of my roller. Fig. 2 is a cross-section taken on line X X in Fig. 1. Fig. 3 is a sectional view taken on the line H H in Fig. 2. Fig. 4 is a detail view of one of the sections of the design material before it is fitted to the roller. Fig. 5 is an enlarged detail showing the method of joining these sections. Fig. 6 is a detail view showing a method of securing the inner sections of wood to the hub. Fig. 7 shows a modified form of fastening for the design-boards.

Similar figures refer to similar parts throughout the entire description.

In the drawings, 1 is the roller. This roller is formed of a series of boards 2, which are tapered and fitted in radially around the hub 3, in which is fastened the shaft 4 of the roller. This construction opposes a perfect resistance to the go or tendency of the wood to separate from the wood to which it is secured due to atmospheric changes of the different pieces of wood, and owing to the taper the requisite strength of the wood is relatively inextensions extend inwardly to the hub 3.

These tapered sections may be secured to the hubs by means of lag-screws or any of the ordinary methods for such purposes. This hub may be constructed, as shown in Fig. 3, with a flange 7, having a bevel-gear 8 on its outer face and a series of ribs 9 on its inner face. These ribs may be arranged to provide sockets for the ends of the extensions 5 and 6, so as to secure the hub as firmly thereto as if it were constructed integral therewith. By using this method of construction it becomes impossible for the roller to slip and consequently blur the impression. The surface of the boards 2 is turned true. The design-boards 10, being in the form shown in Fig. 4, are cut by means of a band-saw, as indicated by the dotted lines 11 in Fig. 4. These sections are then oined at an angle 12, as shown in Fig. 5, the result being that the extreme thinness of the point 13 on the outer part of the joint is such that there is no perceptible joint, which would interfere with the transfer of a continuous grain. The boards 10 are then glued to the outer turned surface of the boards 2. It may be found desirable, however, in practice to hold these boards in position by means of the construction shown in Fig. 6, in which the board 10 is provided with longitudinal slot or groove 14. A bolt 15, having a head 16, adapted to engage said slot, is fitted thereon. This bolt extends inwardly through the board 2 and is provided with a Washer 17 and nut 18, so that it is pos sible to draw the boards firmly down and fasten them securely to the surface of the board 2 by tightening the nut 18, the result being that when this construction is followed a practically true roller is made, which will maintain its true surface under any and all conditions. It may be found desirable in imitating parquetry flooring or wainscoting "to have the grain ofthe sections run in various directions, which, it is obvious, may be done without departing from the spirit of the invention.

Having described my invention, what I regard as new, and desire to secure by Letters Patent, is

1. In a design-roller for graining-machines, the combination with two hubs, of wooden IIO sections mounted on said hubs, said sections extending radially from said hubs, said sections tapering inwardly, flanges on said hubs, means to secure said sections to said hubs, sections of design-wood having the grain running around the roller adapted to form an outer covering for said tapering sections and means to secure said design-sections to said tapering sections, for the purpose set forth substantially as described.

2. In a design-roller for graining-machines, the combination with two flanged hubs, of Wooden sections extending radially from the said hubs, said sections tapering inwardly, an outer covering of sections of design-wood having the grain running in various directions, means to secure said sections to said tapering sections, said tapering sections being mounted in sockets cast or formed u on the hubs of the roller, and a shaft exten ing through said roller, for the purpose set forth substantially as described.

3. In a design-roller for graining-machines, the combination with two hubs, of wooden sections extending radially from the said hubs, said sections tapering inwardly and having an outer covering of sections of design-wood having the grain running around the roller, said sections being joined in such a manner that there will be no break in transmitting the impression of the grain to the printing-roller, means to secure said sections to said tapering sections, and means to secure said tapering sections to said hubs, for the purpose set forth substantially as described.

4. In a desi n-roller for graining-machines, the combination with two hubs, of wooden sections extending radially from the said hubs, said sections tapering inwardly and having an outer covering of sections of design-wood having the grain running around the roller, said sections being joined in such a manner that there will be no break in transmitting the impression of the grain to the printing-roller, said tapering sections being mounted in sockets cast or formed on the hubs of the roller, and a shaft extending through said roller, for the purpose set forth substantially as described.

5. In a design-roller for graining-machines, the combination with two flanged hubs having a bevel-gear out upon the outer face of said flanges, of wooden sections extending radially from the said hubs, said sections taering inwardly and having their outer surace turned true, an outer covering of sections of design-wood having the grain running in various directions, said sections being joined in such a manner that there will be no break in transmitting the impression of the grain to the printing-roller, means to secure said sections to said tapering sections, and means to secure said tapering sections to said hubs, for the purpose set forth substantially as described.

6. In a design-roller for graining-machines, the combination with two flanged hubs having a bevel-gear out upon the outer face of the said flanges, of wooden sections extending radially from the said hubs, said sections tapering inwardly and having their outer surface turned true, said sections being provided with extensions at each end, said extensions extending inwardly and fitting around the said hubs, an outer covering of sections of design-wood having the grain running around the roller, said sections being joined in such a manner that there will be no break in transmitting the impression of the grain to the printing-roller, means to secure said sections to said tapering sections, means to secure said tapering sections to said hubs, and a shaft extending through said roller, for the purpose set forth substantially as described.
